DIRECTION-INDICATOR FOB AUTOMOBILES.

Patented May 8,191?

Application filed March 21, 1916. Serial No. 85,5708.

To (171 whom 'it may conccrn Be it known that I, nannns M. Nasu, a citizen of the United States, residing at (ovina, in the county of Los Angeles and State of- California, have invented new and useful Improvements in Direction-lndica tors for Automobiles, of which the following is a specification.

My invention relates to a direction innicator for vehicles especially motor driven vehicles.

The ordinances of many municipalities require that the driver of a motor driven velittle space, which may be easily installed in any motor driven vehicle and which is within instant reach of the driver for oper ating the same.

\Vith the above and other objects in view which will a1. pear as the description proceeds, my invention consists in the construction, arrangement and combination of parts hereinafter described and claimed.

My invention .will be better understood with the aid of the accompanying drawings which form a part of this specification, and which illustrate a convenient and practical embodiment of my invention.

Figure 1 is a perspective view taken from the rear of the drivers seat showing the dash board of an automobile to which my direction indicator is applied.

Fig. 2 isafront elevation of my direction indicator partly in section.

Fig. 3 is a section on line 8-3, Fig.

Figs. 4. and are sections on lines ll and 5-5, respectively of Fig. 2.

Referring to the drawings, 10 designates the dash board of an automobile. 'On the upper end-thereof, a pair of direction indicator devices 11, 11 are mounted. The construction of, these devices is exactly alike, and therefore it will be SUlllClBIlt to describe only one of them. Referring to Fig. 2 of the drawings which shows the direction indicator on the right, the same comprises a square casing 1:2 in which a large grooved pulley 13 is rota tably mounted on a shaft orpin 14. On the same pin and fast to the largepulley 13, a smaller grooved pulley 15 is rotatably mounted. A flexible member such use cord 16 is fast to the periphery of the small pulley 15 and is connected to a pivoted pedal 17 mounted on the foot board of the automobile. A. horizontal guide tube 18 extends laterally from one side of the square casing 12 to the side oi the car frame of the automobile. said guide tube 18 is an indicator carrying arm 19 provided with an end guide collar 20 secured to the inner end thereof. A stationary bushing 21 in which the outer end of said arm is slidably mounted is secured in the outer end of the guide tube 18. On the inner face, of the collar 20., a flexible member :22 is secured which extends parallel to the arm 19 passing; through a bore 23 of the bushing 21 and over a fixed pulley 2e mounted on the inner wall of the guide tube 18, thence back and through-abore 25 in the inner collar 20 to the periphery of the large pulley 13 to which it is attached. At the outer end of the tubular guide 18, a casing or housing 26 is mounted which is open at the outer end. A direction signal 27 suitably secured to the outer end of the arm 19 is normally inclosed within the casing 26. sired or suitable shape, such as a hand. A

Sliolaloly' mounted in.

-'lhe signal arm 27 may have any de helical spring 28 secured at one end to the outer face of the collar 20 and at the other to the pulley casing 12 tends to hold the signal arm and the signal carried thereby in inoperative position as shown.

I have shown the pulley casings of the two direction indicator devices as placed one on top of the other, (See Fig. 1.) If desired, they may be placed side by side.

From the foregoing description, the operation of my direction indicator will be easily understood. Let us assume that it is desired to use the device on the right; the right pedal 17 is depressed, which will,

through its flexible connection 16 rotatethd small and the large pulleys 15 and 13 in the direction indicated the arrows in Fig. 2. Such rotation of? the larger pulley will wind the flexible member 21 on the larger pulley,

causino the signal arm 18 and the signal carried thereby to move outwardly in the ositions indieated by the dotted lines in ig. 2-. This movement of the signal is opposed by the helical spring Just-as soon as the pressure on the pedal 17 is released, the helical spring-will move the signal arm and signal to their normal inoperative position.

Such moven'ient of the signal arm and the. flexible member 21 seeured thereto will restore the pulleys and the pedal to their original position. 1

It is thus seen that l'have devised a direetion indieatol' \vhieh is extremely simple in eonstruetion and positive in operation. slight pressure 'ol. the Foot on the appropriate pedal will operate the direetion indiea tor, and as soon as the pressure is released, the signal will he moved toits inoperative position within the housing so.

Various changes in the details of the (onstruetion ol my invention maysuggest themsglves to those skilled in the art wlthout departing from the spirit of my invention as detined in the I claim: y

In a direction indicator for"vehieles,'the eomliinatioli 0f. ztpair of tubular casings eaeh easin having-a housing at the outer end thereoi asignal arm slidably mounted in each easing, a signal carried by said arm and normally inelosed in said. housing, a large grooved pulley, a small grooved pulley last tosaid large pulley a flexible member eonneeted to said arms and Wound about the appended claim.

. periphery of the large pulley, a pair of independently operatedpedals, a flexible memher wound about said small pulley and eonneeted to said pedals, a helical spring in eaeh of said, casings acting in oppositionto said pedals for moving said .arm and signal, into inoperative posit-ion.

Tn testimony whereof I name to this speeification.
